Supported external interfaces include Line6 Midi Mobilizer I and Midi Mobilizer II, IK Multimedia iRig MIDI and all other CoreMIDI devices that are compatible with iOS via the USB camera kit on iPad. For CoreMIDI support, iOS 4.2 or greater is required. Now also supports virtual CoreMIDI interfaces.

There’s a bit of feedback on MidiBridge over at http://musicapps.com.br (you’ll need a bit of google translate if you don’t speak Portugese) where a number of users have reported positive results, especially with being able to use the Midi Mobilizer I with newer apps.

Ultimately though, if you download the app and it doesn’t work as well as you like it is possible to get a refund from the iTunes store, but we would hope that anyone experiencing problems would contact us first in case it is an issue that can be solved 🙂
